If the product of power of point (1, 1) and (–1, –1) with respect to circle x2+y2+2px+2qy+4=0 is negative and the circle neither touches nor intersects co-ordinate axes, then the area of region formed by the set of ordered pair (p, q) on pq plane is

If the product of power of point (1, 1) and (–1, –1) with respect

1.	If the product of power of point (1, 1) and (–1, –1) with respect to circle x2+y2+2px+2qy+4=0 is negative and the circle neither touches nor intersects co-ordinate axes, then the area of region formed by the set of ordered pair (p, q) on pq plane is
Answer» If the product of power of point (1, 1) and (–1, –1) with respect to circle $x^{2} + y^{2} + 2 p x + 2 q y + 4 = 0$ is negative and the circle neither touches nor intersects co-ordinate axes, then the area of region formed by the set of ordered pair (p, q) on pq plane is
